Terminal Information Prioritization Across Overlapping Radio Resources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems with dual connectivity supporting multiple radio access systems, conflicts arise when terminal devices use overlapping time domain resources for information transmission, leading to increased interference and decreased communication quality.
Innovation Solution
A method for a terminal device to determine and prioritize information transmission based on priority, either by predefined rules, parameters, or explicit indication, ensuring high-priority information is sent or received while resolving conflicts between different radio access systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If terminal devices use overlapping time domain resources for information transmission in different radio access systems, then radio resource utilization is improved, but interference increases and communication quality decreases
Solution Approach 1:
The patent changes the parameter of resource allocation by introducing priority-based time domain resource scheduling. When conflicts are detected between first information in the first radio access system and second information in the second radio access system, the terminal device determines priorities and selects resources based on priority levels, thereby reducing interference while maintaining efficient resource utilization.
Solution Approach 2:
The patent implements dynamic resource selection by allowing the terminal device to adaptively choose between different time domain resources based on real-time priority assessments. The terminal device dynamically determines which information to transmit or receive on conflicting resources by evaluating priority relationships, enabling flexible and interference-minimized resource usage.
2Adaptability or versatility
If terminal devices use overlapping time domain resources for information transmission in different radio access systems, then system flexibility is improved, but communication quality decreases
Solution Approach 1:
The patent introduces priority as a controlling parameter to manage the trade-off between flexibility and reliability. By assigning priorities to different types of information (first information in the first radio access system, second information in the second radio access system) and using these priorities to resolve resource conflicts, the system maintains flexibility in supporting multiple radio access systems while ensuring reliable communication through priority-based conflict resolution.
3Object-affected harmful factors
If the terminal device sends or receives only high-priority information during resource conflicts, then interference is reduced, but information transmission completeness may be compromised
Solution Approach 1:
The patent extracts and prioritizes critical information by separating information into different priority levels. When resource conflicts occur, the terminal device identifies high-priority information that must be transmitted or received and selectively processes only that information on the conflicting resources, thereby reducing interference while ensuring that the most important information is not lost.
Data Source
AI summary
This application provides an information transmission method and apparatus, to resolve a problem of a conflict between resources used by a terminal device to send/receive information in different radio access systems, ensure successful transmission of information with a high priority, and improve communication quality. A terminal device determines information with a higher priority in first information associated with a first radio access system and second information associated with a second radio access system. Time domain resources associated with the first information and the second information are completely or partially the same. The first information is data information and the second information is synchronization information, or the first information is synchronization information and the second information is synchronization information. The terminal device sends or receives the information with the higher priority.
